OCP CBT Question 693

Please solve the following question.

You are setting up an RMAN retention policy for a critical production database. You need to ensure that backups are kept for at least 7 days and that the database can be recovered to any point in time within the last 7 days. Which RMAN command correctly configures this requirement?

RMAN retention policies define which backups are considered obsolete and can be deleted. A common requirement is to ensure a 'recovery window' exists, allowing point-in-time recovery for a specified duration.

CONFIGURE RETENTION POLICY TO REDUNDANCY 7;

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

CONFIGURE BACKUP OPTIMIZATION ON; CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;

CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '%U' RECOVERY_WINDOW 7;
